Wearable cardioverter defibrillator (WCD) system making shock/no shock determinations from multiple patient parameters

Abstract

A method for a wearable cardioverter defibrillator (WCD) system comprises sensing one or more patient parameters from different parts of a body of the patient by the one or more transducers, obtaining a plurality of physiological inputs from the sensed one or more patient parameters, detecting first aspects from each of at least some of the physiological inputs, generating an aggregated first aspect from at least two of the detected first aspects, determining an aggregate analysis score from the aggregated first aspect, and determining whether the aggregate analysis score meets an aggregate shock criterion. The electrical charge is discharged within six minutes from when it is determined that the aggregate shock criterion is met, otherwise the electrical charge is not discharged for at least 19 minutes from when it is determined that the aggregate shock criterion is not met.

AI Technical Summary

Benefits of technology

The present patent describes a wearable cardioverter defibrillator (WCD) system that can sense patient parameters from different parts of the body and make a shock / no shock determination based on those inputs. The WCD system can detect both first aspects and second aspects from the patient parameters, and generate an aggregate analysis score based on those aspects. This aggregate analysis score is then compared to a shock criterion to make the shock / no shock determination. The advantage of this system is that multiple inputs are considered, resulting in a more accurate and reliable shock / no shock determination.

Problems solved by technology

Some arrhythmias may even result in a sudden cardiac arrest (SCA).

SCA can lead to death very quickly, e.g. within 10 minutes, unless treated in the interim.

Some people have an increased risk of SCA.
